| 摘 要： | 提出了一种基于瞬时无功功率理论的先进静止无功发生器（ASVG）的控制方案。首先详细地对瞬时无功功率理论检测控制信号进行了分析，在此基础上，介绍了无功电流闭环间接控制方案，应用基于瞬时无功功率理论的无功电流检测法实时检测无功电流，提高了系统响应速度。然后简单介绍了ASVG的电路结构；控制器选用TMS320LF2407来实现数据采样、计算和实时控制，满足ASVG实时快速控制的要求，提高了PWM脉冲精度。最后通过Matlab对控制方案做了系统仿真。通过理论论证和仿真分析表明本设计方案是可行的。

| Abstract: | A control scheme of the advanced static var generator(ASVG)is determined.First,the instantaneous reactive-power theory is analyzed,Then,the closed-loop indirect current control strategy is introduced.Based on the instantaneous reactive-power theory,the reactive current is detected in time,and this method increases the speed of systematic response.On configuration of system,the converter's power module based on IGBT is adopted in main circuit;and a TMS320LF2407 is adopted as the main controller to deal with ... |
